Transcript of Electrical Safety in the Home - By Zura.
electricity can be extremely dangerous. There are on average one THOUSAND deaths
and 3000 injuries per year due to electrical accidents. Sources:

in danger of being electrocuted and harmed:
• Replace a switch or a power point.
• Attempt to repair electrical appliances such as toasters or irons.
Consider hiring a trained professional for these kind of tasks. One slight mistake and you could be seriously injured, or killed. There are some jobs that you can do without the aid of a licensed electrician such as:
• Changing a light bulb
• Replacing a fuse
• Resetting a safety switch.
There is always a risk when playing with electricity. Consider watching this short video to gain a small understanding on what not to do and learn some basics of electrical safety. Safety switches and circuit breakers are found in all homes. Once an electical leak is detected, the electricity is then cut off. Circuit breakers provide protection for short circuits and when there is an overcurrent - just like when a power point is overloaded. Safety switches, on the other hand monitor the flow of electricity and detect if there is a problem which may be a risk to personal safety. If something like this is detected, e.g if an electrical appliance falls into the bath, the power will then be turned off within 0.03 of a second!
Did you know:
• If we touch exposed wires, electricity can pass through our body and we become an accidental circuit - exposed wires can also form an accidental circuit.
•Just 50 milliamps of current can interrupt our heart and paralyse the muscles we use for breathing, which will kill us.
•Sweat on your hands can increase the current to your body
The main job of a fuse in a circuit is to protect the wiring and prevent the house from having an electrical fire. A Ground Fault Circuit Interrupter (GFCI) is an outlet which protects people from electrical shock. In conclusion, take complete care when dealing with electricity. It is very tempting to ignore the electrical signs of hazard. Another safety feature in homes is insulation. Insulation is a material, for example rubber or glass, which has a high resistance and therefore does not conduct electricity effectively - only a very small amount of current will pass through. If insulation becomes damaged and wires are exposed, a short circuit, sending large amounts of electricity through the circuit and, if the wires are in contact, it will cause an electrical fire.
So remember: If the wires are damaged, do not try to fix it. Instead, call a licensed technician. r
